In this paper,we introduced what are quasiregular coherent configurations and systems of linked quotients.Then we prove that they are equivalent.As for coherent configurations,the following results are obtained:For any coherent configuration X=(Ω,S),△is a subset of Ω,△(?)Ω,△ andΓ any fiber of X satisfy|△∩Γ|=1we define F:=F(X)is the set contains all △.·Let X be a quasiregular coherent configuration.Suppose that for any φ∈Isoalg(X,X’),any two distinct points α,β∈△∈F,and any α’,β’∈Ω’with φ(r(α,β))= r(α’,β’),there exists an injection f:△→Ω\such that(α,β)f=(α’,β’)and thatΥ(δ,γ)φ=Υ(δf,Υf),δ.Υ∈△Then X is separable and schurian.·A quasiregular coherent configuration with at most three fibers is schurian and separable.·Let(?)be a family of groups with distributive lattices of normal subgroup-s.Then any quasiregular coherent configuration of type(?)is schurian and separable. |
